CHARGING A 12 VOLT BATTERY
This generator can be used to charge a 12 volt automotive or storage
battery by taking the following steps:
Inspect fl uid level of the battery cells. Add ONLY distilled water to any cell
where fl uid level is low. Never add tap water.
1. Use a wire brush to clean battery terminals if corroded.
2. Securely connect the red cable clamp to the positive (+) battery
terminal.
3. Securely connect the black cable clamp to the negative (-) battery
terminal.
4. Turn the Economy switch to the “OFF” position to start battery
charging.
5. Battery is considered fully charged when the gravity of its fl uid is
between 1.26 and 1.28 when measured by a hydrometer.
Note: It is strongly recommended to check the gravity level of the electrode at least once per hour with
a hydrometer to prevent overcharging and to test the battery’s condition. Be careful to follow the hydrometer
manufacture’s instruction.
WARNING!
Battery electrolyte is poisonous and dangerous.
Do not disconnect battery clamps while charging. Batteries produce explosive gasses. Disconnecting the
battery clamps while charging could spark and ignite.
Do not charge battery in an enclosed area.
Never smoke while charging the battery or operating or fueling this generator.
Battery electrolyte contains sulfuric acid. Avoid contact with skin, eyes, and clothing. Always wear eye
protection when charging battery.
If battery add contacts skin, fl ush with water immediately. If it contacts eyes, fl ush with water for 15 minutes
and get immediate medical attention. For internal ingestion, drink large quantities of water or milk, followed by
milk of magnesia, beaten egg, or vegetable oil. Contact a medical physician immediately.
DON’T OVERLOAD GENERATOR
Make sure you can supply enough rated watts for all electronic devices connected to the generator. Rated watts
refer to the power a generator must supply to keep a device running. Surge watts refer to the power a generator
must supply to start an electronic device. This power surge for starting a device usually lasts between
2–3 seconds but this additional output must be taken into account when selecting the electronic devices you
plan to attach to the generator. To prevent overloading the generator take the following steps:
1. Add up the total rated wattage of all electronic devices that will be connected to the generator simultaneously.
2. Estimate surge watts by adding the item(s) with the highest output (it is unnecessary to calculate the surge
output for all devices as they should be connected one at a time).
3. Add the Surge Watts to the total Rated Watts in step 1. Keep total load within generator’s power capacity.
